Single-storey, double-storey, rear and side extension drawings for Roundhay homes — measured to Leeds City Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Leeds City Council granted 83% of the householder planning decisions it made in its latest published year — 4 points below the 87% England-wide householder average. Extensions near Roundhay Park and inside the conservation area are held to the scale and spacing of the original villa plots, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Leeds City Council needs a full application. Roundhay carries at least one Article 4 direction, and conservation areas including Roundhay, Gledhow Valley and Shadwell remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Roundhay is determined against an 8-week statutory target.
Oakwood (Edwardian villas and parades near the park entrance), Street Lane (interwar semis and detached houses), Roundhay Park fringe (grand villas and mansion flats inside the conservation area), Gipton Wood (interwar semis backing onto woodland), Gledhow (Victorian villas along the Gledhow Valley) and Moortown edge (larger interwar and postwar detached houses) — these are the Roundhay pockets our drawings cover most. Heritage designations here include Roundhay, Gledhow Valley and Shadwell. Leeds City Council weighs each proposal against Leeds Local Plan / Core Strategy and the relevant SPDs, where the HMO Article 4 catches house-to-HMO conversions across the ward. Mansion flats and villas converted into apartments ring Roundhay Park, and flats hold no householder permitted-development rights.. On roofs the borough is hipped and gabled roofs on the villas and interwar semis and pitched slate roofs on the Edwardian houses, over large Victorian and Edwardian villas around Roundhay Park, interwar semi-detached and detached houses, purpose-built and converted mansion flats and postwar detached houses on the northern fringe.
Roundhay homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from large Victorian and Edwardian villas around Roundhay Park, interwar semi-detached and detached houses, purpose-built and converted mansion flats and postwar detached houses on the northern fringe, so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Leeds City Council judges every one of them against Leeds Local Plan / Core Strategy and the relevant SPDs, weighing footprint, height and the impact on the house next door before it looks at the elevations.
That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. Extensions near Roundhay Park and inside the conservation area are held to the scale and spacing of the original villa plots, so we design around it from the first sketch rather than discover it at validation.
Roundhay also protects whole streets — Roundhay, Gledhow Valley and Shadwell among them. Roundhay is named within the inner-Leeds HMO Article 4 area, so converting a house to a small (C4) house in multiple occupation needs planning permission rather than permitted development. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.
Plenty of Roundhay extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Leeds City Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Leeds City Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification or a full householder application.
Below is Leeds City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Leeds approves most householder schemes in Roundhay, though conservation-area character around the park and the HMO Article 4 shape what gets consent. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Across Oakwood, Street Lane and Roundhay Park fringe, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's large victorian and edwardian villas around roundhay park, a side-return infill frequently pairs with it to square off the plan; on wider postwar detached houses on the northern fringe, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The HMO Article 4 catches house-to-HMO conversions across the ward. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Leeds City Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.
We draw extensions on every street in the borough. A few of the neighbourhoods where Roundhay projects come up most often:

The right extension in Roundhay depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.
| Extension type | Permitted development? | What it adds | What Leeds City Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
Route depends on your street — conservation areas such as Roundhay and Gledhow Valley and Article 4 directions can remove permitted-development rights.
A fixed process built around how Leeds City Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Roundhay postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live Leeds City Council decisions.
We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Leeds City Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Leeds City Council issues its decision.
Not always. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development. In Roundhay you will need to apply to Leeds City Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Roundhay and Gledhow Valley.
Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Leeds City Council and a neighbour-consultation period, and it does not apply on designated land such as Roundhay's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to Leeds City Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Roundhay address specifically.
A householder planning application in Roundhay runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Leeds City Council is the decision-maker.
Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Leeds City Council's building control or an approved inspector can sign the work off. This applies to your Roundhay address specifically.
Every house and brief is different, so we price each Roundhay extension individually and send a fixed, no-obligation quote back within one working day.
